At

their inner ends, these rods areformed with mating bearing portionswhich `fit about the crank pins25 and 26 and are formed toprovide cross heads 31 slidable between the pairs of guides 27. Securing, the `bearing portions of each cross head together are cap bolts 32. Thus, the piston rods are operatively con* perceived, thel cross lheads 31 willcooperate `with the guides27 forlimitingthe crank pins 25 and 26 to rectilinear movement in planes radial to the crank shaft.l Suitable pistons tov the outer ends4 of the piston rodszfor reciprocation in-the cylinders attached to the bosses 29 of the Vcasing 10.

As will now be seen in view therfore'- reciprocate, the thruston the crank pins 25 and 26 will, since said pins are limited against travel in a circular path, be :communicated to the crank shaft 23 and consequently to the stub shafts 13 for causing said stub shafts to rotate.Y Rotation of the stubshaftswill effect the travel ofthe crank( shaftfin a circular path about the axes of said stub shafts, with the result that the' rectilineark throw of the crank pins will be accommodated by` the eccentric throw of the crank shaft sor that the crank pins may travel in straight lines as the crank shaft revolves about the axesy of thev st-ub shafts. Furthermorasince'the eccentric throw of the crankshaft isequal to the edective length ofthe cranks, aspreviously noted, the eccentric throw of the crank shaft will serve to double the crank pinthrow with ra corresponding increase in length of piston stroke for any given'4 crank length. Figure 2 showsthe crankpin 25at the middle of its stroke in one direction, at which time the crank pin 26 is, as shown in" Figure 3, at oneend of its stroke ready to return in the opposite direction. Figure 15 shows the relative disposition of the crank pins at such time while Figure shows, by full section lines and dotted sections, the typical rectilinear travel of one of the crank pins. 4

In Figure 7 ofthe drawings, I have illus-'- trated the present improvements embodied in a machine adapted to a rotary engine. A casing 33 is employed. This casing is identicalv y with the casing 10 with the' exception that the flanges 11 of thelatter casing are eliminated. 4 The cross rod',l7',thegears. 1,8, cross shaft 19, and pinions 20, as illustrated in the prior embodiment of the invention, are also eliminatedly-Extendingpat `the ends of the casing 33 are stub shafts 34 identical with V`the shafts'13 and extending through the shafts '34 isa crank shaft 35 identical with the crank shaft 23.j Connected'with thecrank shaft are piston `rods 36 corresponding to the pis- ,ton rodsr30, and mounting the stub shafts 34:

laresupports 37 whichare similar to lthe supf ports 15 landare provided attheir upper ends with bearings 38 journaling the stub shafts.

vExtending through the stub y'shafts and through'saidbearings are pins' 39 lockingthe stub shaftsl against rotation'. Otherwise, this nembodiment kof the invention is identical with tlievprior embodiment and, as willjbe per- Vceiv,e lin view of the foregoing description,
